Eosinophilic meningoencephalitis with permanent sequelae

The youngest patient with eosinophilic meningoencephalitis to be reported from Australia, an 11‐month‐old girl, is presented here. The diagnosis of angiostrongyliasis was based on the exclusion of other possibilities, the strongly‐positive results of serological examination and the findings of an environmental survey. Clinical signs of serious brain damage, with persistent blindness, profound mental retardation, spasticity and epilepsy more than three years later, indicate that this infection is not always as benign as is considered generally.
